FOr what it's worth -
I agree that it could be set up in the database -
Overridden by device support -
Or not used at all by device support.
It is necesary to remember that as of 3.13, the address can be changed
during operation. We either need to have device support recompute this
based on the signal each time the record is processed - or have special
processing in the record for this fireld and recompute the SHFT when the
signal changes. As the second suggestion required some changes to Base -
I opted for only using the signal and computing the mask each time the
record was processed - this takes two extra instructions (which is
loathsome to cycles mongers like myself) but supported the ability to
change addresses during operation - which is nice. I think we need to
change base to support recomputing MASK and SHFT wheneever the address
field is changed.
